Oct. 1932. G, w WAGNER j RAIL JOINT Filed July 16, 1951 Patented Oct.v 18, 1932 UNITED STATES GEORGE W. WAGNER, or MARILINTON, WEST VIRGINIA RAIL JOINT Application filed J'uly 16, 1931. Serial No. 551,217. s s p cated in the bolt holes 4 of the walls 3 and This invention aims to provide a rail chair which will have unusual strength against downward fleXure at the meeting ends of the rails, it being'l possible to locate theV bolts properly, and adequate provision being made for spiking the chair to the tie.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

"5 details of construction hereinafter described :f-. from the spirit of the invention.

In the accompanying drawing Figure 1 shows in side elevation, a device constructed in accordance with the invention;

Figure 2 is a section on the line 2 2 of Figure 1;

Figure 3 is a section on the line 3- '3 Vof Figure 2.

The device comprises, in a rail joint, a chair including a base plate 1 having oppositely disposed overhanging wings 2 provided on their inner edges with upwardly extended walls 3 having bolt holes 4. Rails are provided, and have their ends received in the chair, the combined thickness of the walls 3 and the web 5 of the rails approximating closely the width 6 of the ball 7 of the rails, to give the walls 3 strength .to withstand downward flexure.

The chair is provided with outwardly projecting integral buttresses 8 which extend, from the outer edges 9 of the base plate 1, upwardly and inwardly, as at 10, across the wings 2, and upwardly, as at 11, along the walls 3. The buttresses 8 are located at the end surfaces 12 of the rails, the upper ends of the buttresses being spaced, as at 14, from the upper edges of the walls 3, to leave room for wheel flanges.

Inner bolts 15 and outerbolts 16 are lo- Vengage the webs 5 of the rails.

The but-` tresses 8 taper, as at 17, in width, as they extend upwardly, thereby to permit the inner bolts 15 to be disposed suiiiciently close to the enld surfaces 12 of the rails. Those parts of the outer edge portions of the base plate l which lie on opposite sides of the buttresses 8 constituting spike flanges 18 having notches 19 to receive the spikes 2() which hold the chair on the tie 21.

The chair has been designed with the specific view of making it unusually strong immediately below the end surfaces 12 of the rails, and this is accomplished by means ofthe buttresses 8,. and by thickening the walls 3, so that the combined width of the walls 3 and of the web 5 will approximate the width 6 of the ball 7. The tapering of the buttresses, at 17, permits the inner bolts 15 to be located properly. There is no chance that the wheel flanges will strike the buttresses 8, and the anges 18 afford a means whereby a chair may be spiked down. Because the .buttresses 8 exy tend outwardly to the extreme outer edges 9 of the base plate 1, the inner ends of the spike flanges 18 are connected to the wings 2, the spike flanges being reinforced accordingly.

Having thus described the invention, what is claimed is In a rail joint, a chair comprising a base plate having oppositely-disposed overhanging wings provided on their inner edges with upwardly-extended walls having inner and outer bolt holes, the chair being provided, on each side, with a single outwardly-projecting integral buttress located midway between the inner bolt holes, at equal distances from the outer bolt holes, and at equal distances from the ends of the base plate, the buttresses extending inwardly from the extreme outer edges of the base plate, upwardly and inwardly across the wings, and upwardly along said Walls, the upper ends of the buttresses being approximately iiush with the upper edges of the inner bolt holes and being spaced from the upper edges of said walls, enough to leave room for wheel flanges, the buttresses taperthe inner bolt holes can be located close -to- Ibo gether and at the same time have the buttresses afford a maximum amount of reinforcement at their lower, outer ends, and having upper ends of considerable width, compared with the distance between the inner bolt holes, those parts of the outer edge portions of the base plate which lie on opposite sides of the buttresses constituting spike flanges having spike notches, al1 of which are disposed beyond the ends of the buttresses, the outer edges of the buttressesand the outer edge of each spike flange being disposed in the same straight line with the outer edge of one buttress.

In testimony that I claim the foregoing as my own, I have hereto aiiXed my signature.

GEORGE w. WAGNER.
